Magic Crystal
Magic crystals are the physical source of mana used to charge wands and wizard armor, as well as being an ingredient in numerous crafting recipes. They are central to wizardry's gameplay, and in fact the first step in wizardry is to gather magic crystals.
Obtaining
Magic crystals drop from crystal ore when mined, which is their primary source. Smelting crystal ore in a furnace yields a single magic crystal. They can also be crafted from crystal flowers, which can be found growing on grass at the surface of the overworld, and from crystal blocks, which are their storage block counterpart. Magic crystals are also dropped by evil wizards when killed, and can be obtained by trading any spell book with a wizard. Additionally, they can be found as loot in dungeon chests and some wizard towers.

Usage
Magic crystals are used primarily to charge wands and wizard armor in the arcane workbench or via mana flasks. They are also used in most of wizardry's crafting recipes, including being crafted with a book to obtain The Wizard's Handbook. All wizard trades (except exchanging a spell book for crystals) cost some number of magic crystals along with another trading item (like gold).
